To all 'whom t may concern Be it known that I, MATTHEW T.. LONG, a citizen of thev United States, residingV at Helena, the county Oi? Alfalfa and" State of Qltlahema, havelinvented a new and useful Ti-raBolting Machineodi which thel fellowing is afspeciication.

This invention relates to an automatic machine which i'sparticularly adapted .for applying nuts to and removing nuts from the tiresV or wheelsand other articles, although the machine may be used in many other connections iii? desired. v One oi the objects of the invention is to provide a machine of the character indicated which isr adaptedto operate on `wheels i of many different sizes or' diameters.,

A further object of the inventionL isj to provide means fory counterhalancing the weight ot the wheel' so as'to permit it to be handled with great facili-ty and' by the expenditure of little effort onthe part of the operator of the machine.

A further object of the inventionl is to provide means for adjustably gaging the position of the rimof the wheel so'- as to aline it accurately andi positively with the nut removing or applying mecllianism, the adjustable character ot' the gaging mech-anismpermitting the machine of the present invention to be used with` wheels having rims of different thicknesses and' other charm acteristics.

A further object of the invention is to pro vide wrench mechanism which is adaptedf either to apply nuts tol or to remove nuts from the wheel which is being acted upon.

A further object of the invention is to` provide means for automatically feeding nuts and the like to the wrench mechanism during the Operation Oi applyingnuts tothe wheel rim, said feeding mechanismfbeing adapted to be moved intoy and out ot operation and'y to be heldf properlyeither'inl operative or in inoperative position` A further object ot the invention is to= provide adjustable mechanism which is adapted to be employed for clampingl the bolt in position in the tire during the `operv ation of. applying or removing nuts,l wheneverl the necessity for such mechanism arises, Iit. being understood that the mechanism ,herein provided Jfor the purpose mentioned, can be used for many other purposes.

With thel foregoing and other objects in ,view which will appear as the description fproceeds, thev invention resides inl the combination and arrangement of parts and in the :details of construction hereinafter de- 'scribed v and claimed, it being understood that changes in the. precise embodiment of iiiventionl herein disclosed can be made l withinv the scope'of thev claims without dei parting tromi the spirit of the invention.

l `Like reference numerals indicate correspondin-g parts in the diiierent figures of the drawings.. i

The particular embodiment of invention herein disclosed@ briefly outlined, comprises a suitable' standard or frame which carries the operating parts of the machine. The supporting means for the wheel which is being operated upon, preferably consists of a studi-shaft which is adapted to fit into the hubv of the wheel so as to hold the wheel ini suchI position that it may be readily ,rotated and that its rim will rest upon a For the purpose of facilitating the up-l nism the weight of the wheel is accurately.

counterpoised and the operator can therefore raise and lower the wheel with the expenditure o-f very little effort. The wrench mechanism preferably is rotary, and is provided with a removable plug, whereby to facilitate the operation of applying the nuts, thefplug being removed from the wrench mechanism when it is desired to takev oil.'

`nut-s, so as to permit the nuts to drop through the wrench mechanism as they are screwed olf.V

Y Suitable mechanism is provided for feeding nuts to the wrench, and a vertically adjustable device is provided for clamping the bolts rmly in the rim of the tire so as to y otherwise'secured to theV casting 3 suitable manner. table 4, has fixed thereon a gear-wheel 14V hold them immovable during the operation of applying or removing nuts.

Having thus briefly outlined some of the principal features of the Ymachine in. order to 'facilitate' the understanding thereof, a specic description of the device will now be given., v Y Y lThe frame of the machine preferably consists of a basel and-a standard or upright 2, which parts may be of any suitable form' .and construction;

Bolted .orl otherwise secured in any suitable manner to the upper end of the standard 1 is a casting 3 which preferably is formed with a lower extension producing a work table 4. The casting 3 is also formed with an upper extension or arm 5 kin which is journaled a shaft 6 having on the upper end thereof a bevel gear 7 meshing with a large bevel gear mounted on a shaft 9 and provided with an operating handle 10 mounted eccentricallyon a wheel 11- which is xed on the shaft 9. The shaft 9 .is suitably journaled in` side arms 12 formed onV a casting 13 which is bolted or in any The shaft 6, below the whichV is in mesh with a gear wheel 15 which operates the wrenchmechanism for removing and applying nutsfrom the inner side of the rim of a wheel. The gear wheels l14 and 15 are located in a suitable housing 16. The wrench mechanism preferably consists of a tubular elementV 17 which extends through vthe .gear wheel 15 in a vertical directionand is lfixed therein yin any suitable manner so as to rotate therewith, the upper end of the tubular member 17 terminating approximately flush with the :upper surface moved of the operating table 4 as shown. The tubular member 17 at its upper end is formed with a square or angular bore to receive the nut which is to be applied or re- Y Adjustably mounted within the wrenclrmember or tube 17 is a plug 18 which is formed with a stem 19 that extends through a cap 20 screwed or otherwise detachably fitted into the lower end of the wrench member 17. A coil spring 21 preferably surrounds the stem 19 between the cap 20 and the plug 18. In the operation'of the device, it is to beiunderstood that the wheel which is to be acted upon is suit-ably held at its center below the table 4, so that its rimrests upon the uppersurface of the table 4. If it is desired to remove nuts from the bolt.l of the wheel rim, the cap 2O and plug18 are removed from the Wrench member 17 so as to provide a continuous vertical bore through said wrench member. The nut t0 be` removed is then fitted into the upper end of the wrench member 17 and the handle 10 of the wheel 11 is given a turn, whereby through the gears 14, and 15 the wrench member is rotated so as t0 unscrew the nut. As soon as the nut is entirely free from the bolt on the wheel it drops through the wrench member 17. The wheel can then be rotated one step so as to bring the next nut into posit-ion within the wrench member 17. The stem 19 of the plug 18 preferably is provided with a nut or other stop member 22 which serves to prevent the spring 21 from throwing the plug too far upward within the wrench member 17 When the machine is to be used for applying nuts to the rim of a wheel, the nutfeeding mechanism 25 is brought into play, it being understood that when the wrench 17 is used for removing nuts, the nut-feeder 25 isswung backward into inoperative pcsition so as not to interfere with the operation of the wrench 17 in removing nuts. The nut-feeding device 25 preferably consists of a vertically extending trough member, that is, a member which is approximately semi-circular in cross section. At its lower end the nut-feeder 25 is bent rearwardly as indicated at 2G, and an opening 27 is cut through the rearwardly bent extension 26 so as to provide a space for the nut to drop through. The nuts 28 are held upon a vertically extending rod or guide 29 which is detachably engaged at its upper end between a pair of nuts or bolts 30 and 31 suitably held in position within the device 25 by means of the bolt 32. At its upper end the nut feeder 25 is pivotally mounted at 33 upon the casting 13. Pivotally mounted on the same fulcrum 33 is an arm 34 which isv weighted at its upper end as .indicated at 35 and at vits lower end is bipremsa "fui-cated to produce two arms 36 337.( The weighted 'arm 34 Y is adapted -to hold the l nut feeder 25 lyieldingly in either lopera-E` tive or inoperative positionbybeing iiierelylv swung across its center from "the ipositionv shown in Fig. 3 to a position wherein thea weight is located in :advance Aof the pivo't .point 33. lli/*hen the weighted 'arm 34 is in theposi-l; tion illustrated inli'gz 3, -thefprojection or 1 boss member 37 thereof :engages "the rear portion of th-e nut-'feeder 25 and serves nor- 5 Ymally to swing the same forward inftofth'e` .position shown in Fig. 3 so as to perm'itjtheg` vbottom-*most nut to 'drop into the openingI fit ythe same time, the nut feeder 25 is yieldingly held whereby, whenthe wheel rim is pushed back into position over ythe wrench 17, `said wheel rim likewisepushes the nut feeder 25 out ofthe way. The rear'- ward extension 26 of the nut-feeder l25 is adapted, when pushed backwardly 1in the manner described, to engage or abut against a washer 40 which surroundsfthe shaft'G and is eccentric to said shaft. By 'rotating the eccentricwasher 40`uponl the "shaft G, the distance to which vthe Inutifeede'r '25 can be pushed backward by Vthe wheel can bel nicely adjusted. iWhen in the position@ shown in Fig.. 3, the washer 40 permits the i feeder and consequentlyfthe wheel rim tol be pushed backwardso'me distance upon the? ar1n4; but if the washer L.t0-,were :turned in the other position, the nut feeder 25 could only befpushed backwarydto alimited eX-j tent. The eccentric washer 40 thus serves as means for 'limiting 'the movement of the wheel rim upon the table 4, and lthus serves as means 'for alining rims o'f'dilferent thick-- nesses and character Aproperly above the wrench. member 17. "For 'example when a wide or broad-gage wheel rim is being operated upon, the .eccentric washer"40will be adjusted as 'illustrated inFig. 3; but when a narrow rim is being operated upon,ra'ndk it is necessary to center thefnutsfthereof above the wrench 17, the eccentric washer 40 is rotated so that the thick or wide portion thereof will abut'against the rearward* extension 2G of the nut' feeder25. Therefore when the narrow wheel rim isshoved backward on the .table 4, `it will onl-y be able to push the nut feeder 25 a A'short distance backward before the extension 26 abuts against the eccentric washer y40, thus indicating the extent to which the Vwheel rim Ishould be pushedbackward in orderto center the nuts thereof 'abovethe wrench 17.

When it is desired `to remove nuts, .instead of applying them, it is ldesirable ,that the nut-feeder 25 be'movedentirelyoutl ofthe way. In order yto accomplish 'this result. the weighted `lever 34 is thrown forward;

4arm 54 connected with the table 4.

lso thattlie arm 36 'ft-hereof bears against the forward portion of thenut feeder 25 and Acauses the rlowe'rend thereof to swing backward against 'the thin portion of the `washer 40, thus holding the nut feeder 25 in inoperative position so long `as the weighted lever or a'rm'34 is held Vwithits weight" 35 in advance of the pivot point 33. The plug 18 is (removed from thewrench 17 during 1 nuts 'are to vbe applied, the plug' 18 is replaced within the wrench 17 and the Qweightedflever `35 is `thrown over into the position showninFig; 3fso 'as to cause the Y Anut yfeeder 25 to 'lie normally vin position above fthebwrench 17, saijdnut feeder being merely pushed back from time to time when the wheel rim'isshove'd into place `The 'forward movement of the nut feeder 'p25 is-limitedbywmeans of al chisel ork other The chisel 'is mounted upon the end lof fan arm "46' which, as shown in Fig. 1, is ,bent

upon itself in the form lof a loop and eX- .tends downward through the arms 13, 5

andl4 of thecasting 3 and is slidably mounted therein. At .its lower end,'the` arm 4G is pivotally connected at 47 with afoot vtrea'dle 48 whichis fulcrumed at 49 upon the standa1d'2.v In screwing nuts on the bolts the bolts sometimes will rise in the rim so as to render it .difficult to fit the nuts thereon. In orderl'to avoid 'this difficulty the operator places his foot upon vthe treadle 18 which thereupon draws the chisel 45 down into .position to rest securely on 'the head of the bolt thus holding .it properly in position to receive/.the nut. 'The chisel45 can likewise be employed `in removing nuts. The chisel .45 is normally held in the raised position illustrated in the drawings by means such asthe counter-weight 50 shown best in Fig. 2 'of `the drawings. The counter-weight 5() is adjustably mounted at 51 upon an arm 52 which is fulcrunied' at 53 upon a depending rl`he upper end ofv theV lever 52 is fulcrumed at 55.011 a collar56 which is mounted upon the `arm or. rod46 which carries the chisel 45. `It will be obvious that the counter-weight 50 holds the' chisel 45 normally in raised position.

The means for which is being operated upon preferably includes` a stud 'shaft 60 which is connected with 'a collar 61 adjustably mounted upon a sleeve 62, the adjustment of the collar G1 `being se'curedbyj means of a set` screw 63. The 'sleeve`62 is loosely mounted upon the Y supporting the wheel thisoperation of taking offfthe nut.` Ltheir 'the operation is tofbe reversed,fthatis, when rod 46, so that thesleeve 62 and the rod 46 can operate independently of each other. The sleeve 62 is yieldingly supported by means of a counter-weight 64 which is adjustably vconnected at 65 with a lever 66, fulcrumed at 67 upon an arm 68 which depends from .the table 4, the lever 66 being fulcrumed at 69 upon a collar 70 fixed to the upper end of the sleeve 62. By adjusting theweight 64 upon the lever 66, the

` f weight of anywheel which is mounted upon thehub 60 as indicated in the dot-ted lines `,Can be counterpoised. The adjustment of the stud-shaft 60 upon the sleeve 62 permits Vwheels of different diameters to be employed the distance which the stud-shaft 60 is normally located away from the table 4 depending upon the diameter of the particular wheel vwhich is being operated upon. It

be seen therefore Vthat Vthe machine of the ,present invention is adapted to operate `with wheels of' different weights, different sizes andl diferent'ybreadths. By counterpoising. the weight of the Wheel, the oper- .r ator can readily move itup and down and shove it on and pull it off of the table 4 during the operation of removing or applying .Y nuts.
